DEVICE FOR HEATING BY ELECTRICITY.

Specification of Letters Patent.

Patented Apr. 5, 1921.

Application filed October 4, 1920. Serial No. 414,647.

To all whom it may concern:

Be it known that I, ANTONANGELO NE- GROMANTI, subject of the King of Italy, and resident of Milan, Italy have invented cer tain new and useful Improvements 1n and Relating to Devices for Heating by Electricity, of which the followlng 1s a speclfication. 7

The present invention relates to a device for heating by electricity.

The object of the invention is to provide an arrangement of parts whereby the heat prosection of the device combined with the stove.

Fig. 2 is a plan view partly in section of same.

Fig. 3 represents a sectional view of the electrical heater.

Fig. 4 is a plan view of said heater the cover of which is removed.

The combined construction comprises the base 1 the walls --2 and the cover A chamber 1 is formed within said structure, said chamber being closed within walls and ceiling -5. Said chamber is filled up with heat-storing material as silicon-sand and the like.

Within said storing material, electrical heaters 6 are embedded said heater being constituted in any known form and preferably comprising carbon powder 7- inclosed in flat boxes 8 made of iron enameled in the interior to isolate said powder.

Copper bars -9 fitted in intimate contact with said powder and emerging from said boxes into the form of laminated contacts -*10- are suitably isolated from the metallic walls and constitute the terminals of the heaters.

Said heaters through their terminals are electrically connected to the conductive bars 11 which are in electrical connection with the electric wires 12-.

Within the heat-storing material is embedded a spirally shaped pipe 13 one end of which issues from the stove at 14 and is connected to the outlet of a centrifugal pump 15- the other end being connected to a collecting pipe 16- mounted ibove the ceiling 5 of the heating cham- From said collecting pipe depart pipes or columns -17 the upper ends of which are connected to receptacles --18- the covers of which are made of corrugated metal. 7

Said receptacles or secondary heaters are lodged in suitable recesses of the cover 3.

From another point of the wall of each receptacle or rather from the bottom of same depart the pipes 20 which communicate with the collector 21- and from said collector a pipe -22 returns to the pump.

The liquid driven by said pump is preferably of a kind having a high boiling point oil, Vaseline, glycerin, paraffin and the Tgle pump is driven by an electric motor 2 On the ceiling -5- and between the latter and cover 3 an oven -23 is formed vertically crossed by the columns 22 and surrounded by the collecting pipe 16.

24. is a door.

Between the walls -4t and the walls of the stove a water jacket may be formed which should catch the heat tending to be wasted. 25 is a cock for theflow of the heated water.

26 are valves actionable from outside to regulate the flow of the liquid and the conveyance of heat to the secondary heaters.

Having now particularly described the nature of my invention and the manner in 92 t Y rev 1,091

which the same should be performed I cumulating material to store the heat pro-.

duced by said heaters, a circulating pipe containing a liquid with high boiling point, said pipe having a spiral section embedded in said accumulating material, a pump in serted in said circulating pipe, branches in iii said circulating pipe to convey the liquid to receptacle for Which the heat is intended, and valves to regulate the flow of heated liquid from and to said receptacles.
